It features 3 straight flutes and a plug chamfer, making it suited for through-hole tapping operations where chips can exit freely ahead of the tap. Manufactured from high-speed steel (HSS) with a bright, uncoated finish, it delivers consistent thread quality in light-duty to medium-duty production and maintenance applications. Overall length is 1-15\/16 inches with a thread length of 5\/8 inches. Licensed machinists, tool-and-die makers, and maintenance technicians are the primary users of this tap.\u003c\/p\u003e\u003cp\u003eThis tap is suited for threading 5-40 UNC holes in aluminum, cast aluminum, cast iron, high-carbon steel, low-carbon steel, and medium-carbon steel. The plug chamfer (approximately 3-5 thread lead) allows it to start easily in a pre-drilled hole and is appropriate for both through-hole and deeper blind-hole applications where some thread runout is acceptable. It performs reliably in both manual hand-tapping setups and light machine tapping operations on drill presses or CNC machining centers with appropriate tapping attachments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-40 UNC thread form with right-hand thread direction and H1 thread limit for controlled fit tolerance\u003c\/li\u003e\n\u003cli\u003e3 straight flutes for chip clearance in through-hole tapping applications\u003c\/li\u003e\n\u003cli\u003ePlug chamfer provides easy starting and smooth threading in a variety of materials\u003c\/li\u003e\n\u003cli\u003eHigh-speed steel construction offers good wear resistance for general-purpose tapping\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for use with standard cutting fluids\u003c\/li\u003e\n\u003cli\u003eNo coolant-through requirement simplifies tooling setup\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for any application requiring a 5-40 UNC straight flute plug tap in high-speed steel.

Secure the workpiece and ensure the tap is aligned perpendicular to the drilled hole to prevent tap breakage. Apply an appropriate cutting fluid for the material being tapped. In machine tapping, use a tapping attachment or floating holder to reduce the risk of thread damage and tap breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 5-40 UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-15\/16 inches (1.937 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 5\/8 inches (0.374 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.141 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Length\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSquare Size\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 0.7449 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Aluminum, Cast Aluminum, Cast Iron, High-Carbon Steel, Low-Carbon Steel, Medium-Carbon Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 102\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1003100\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51739707867442,"sku":"1003100","price":22.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba03d406702fd9c25d1a86a86167f7ab.jpg?v=1788818073","url":"https:\/\/voomisupply.com\/products\/osg-1003100-straight-flute-tap-5-40-unc-hss-plug","provider":"Voomi Supply","version":"1.0","type":"link"}
